Plumbing Antifreeze - Mouse bacon?

[Bertiboo]

I was out checking my Rv interior mid winter, and discovered signs of mice. On looking deeper, under a dinette seat where our water pump, heater, etc. resides I saw that a partial container of plumbing antifreeze was empty, and in shreds. See pic! Unfortunately the mice also chewed up a couple of the PEx pipes to get more antifreeze, so I have some repair work to do.

I tried the non-antifreeze method last year (air pressurizing and blowing out system) and missed a spot, ended up replacing a toilet base (thetford model where the water inlet pipe is a molded part of the whole base). But I’m quite unhappy that antifreeze draws the mice in to cause harder to repair damage. Is there any sour antifreeze out there?

Well, there is one good side of the problem. The Antifreeze will kill them.

If this was the propylene glycol antifreeze like for the plumbing, it may not be fatally toxic, even straight out of the bottle.


They ate the top of the bottle also, so maybe it was the plastic they actually wanted to eat?

Looks like that brand's mix contains 10% to 30% Ethanol. https://web.chempliance.com/MSDS/Ope...hx?DocID=57261 The rodents would get intoxicated I'm sure. The RV type antifreeze probably wouldn't kill them but the plastic consumption might.

Dealing with mice in your RV can be quite a hassle. I can understand your frustration with them being attracted to plumbing antifreeze.
